Odpravljanje težav
št. | Fenomeni | Razlog | Rešitve |
1 | Komunikacija z Modbusom ni uspela | Modbus LED Status: LED is off: received no data LED is blinking: the Modbus configuration is not the correct | Preverite povezavo. Preverite konfiguracijo Modbusa: naslov, hitrost prenosa v baudih, pariteto. |
2 | Časovna omejitev Modbus | Na liniji se pojavi šum | Konfigurirajte Baudrate 9600 in uporabite zasukani par z zaščito pred motenjem |
3 | Senzor je odklopljen | Senzor in LFC128 sta izgubila povezavo | Checking connection Check sensor type (LFC128-2 only connects to 0-10VDC / 4- 20mA analog sensor type) Check the switch to see if it is turned on correctly Check that the sensor connector is correct AI1 |
